When learning statistics, one of the most fundamental yet usually grossed over concepts is that of **variance** (i.e. the square of the standard deviation in normal distribution). As we know, virtually all statistical operations which measure deviations of individual values from the norm involve adding the **SQUARED differences between the two numbers**. However, very few instructors could explain why we have to use squares rather than just the absolute values of the difference (or other even powers such as 4, if the intention is to avoid the negatives). This tutorial shall cover this in a convincing manner. Secondly, while we all know the variance of a SAMPLE is arrived by dividing (n-1) of the sum of squared differences, where n is the number of observations, few can articulate the rationale behind it. This tutorial shall also prove step by step why this is case, so after this you could appreciate the logic behind this ingenious insight instead of just reciting it like a medieval myth.

**The Behavior Gap: Where Products Win or Lose** Teams today have more data than ever, and yet many still struggle to understand why customers adopt, engage with, or abandon their products. Teams sprint, ship faster, and chase more signals… all while metrics stall and confidence drops. The missing piece isn’t more data. It’s often the behavioral insight between the metrics, explaining why the numbers move in the first place. Dashboards can tell you what customers did, but understanding why they did it (and how to influence what they do next) requires a deeper blend of insights. This session is about closing that gap. Drawing from real-world experience designing and scaling products as [ZoCo Design](https://zocodesign.com/)’s CEO, [Lacey](https://www.linkedin.com/in/laceypicazo/) will share how to cut through the noise and identify the insights that actually change behavior—moving people, and moving metrics. You’ll learn: * Why understanding customer behavior is a quant and qual challenge * How to spot the signals that actually predict behavior change * Where AI accelerates insight, and where it creates distraction * How to get meaningfully closer to customers, without adding more tools This talk reframes how to evaluate performance and identify what levers actually improve it, helping your team to make smarter bets with greater confidence. Every meaningful outcome is driven by behavior change. And when you know how to design for behavior, you stop guessing, and start building things that work. **About Our Speaker** [Lacey Picazo](https://www.linkedin.com/in/laceypicazo/) is the Founder and CEO of ZoCo, a healthcare product studio that turns complex, high-stakes ideas into products that drive real-world adoption. She partners with healthcare organizations to uncover critical care delivery insights, focus product strategy through behavior design, and build solutions that patients and providers actually use.

Join Guest Host Jeff and the group as we get together to see the historical drama, PRESSURE! Brendan Frasier, Andrew Scott and Kerry Condon star in this film about the tense and dramatic days leading up to the D-Day invasion! Here are details, a trailer and our plan for this event: DESCRIPTION: The film follows General Dwight D. Eisenhower and Captain James Stagg n the tense 72 hours before D-Day. With the fate of the free world in the balance, they face an impossible choice: launch the largest and most dangerous seaborne invasion in history or risk losing the war altogether. It is directed by Anthony Maras and based on David Haig’s 2014 stage play. The film stars Brendan Fraser, Andrew Scott, Kerry Condon, Chris Messina and Damian Lewis. TRAILER: https://www.youtube.com/watch?v=xcPgrKoXe_c PLAN: We’ll plan for a 7pm-ish showing and will meet in the bar area about 30 minutes before showtime! Once showtime is announced, please purchase your ticket in advance and list your seat number in the Comments section of this event! Exact showtime and complete details will be confirmed and announced as the date gets closer! Look forward to seeing you there, Jeff P.S. from Dan: THANK YOU to Jeff for hosting this event!
